I have a glycol question and could use some help figuring this out. I have a keg fridge with an insulated beer line out the top with a 5-6 foot unrefrigerated but insulated run to a tower faucet. As the temperature gets warmer the foam in my keg increases. I have narrowed to cause down to the line as the first beer I pull is foamy and if I pull a second immediately after, it is not. Let the keg sit for 10 minutes and you get 3-4 inches of foam again. All this tells me that I need to refrigerate my lines.
I have looked on this site for ideas on how to do this but when I built my bar I made the tolerances very tight so anything I do must fit in a small space. The beer line runs out the top of the kegerator and makes a 90 degree turn, follows a channel to the edge of the kegerator, through an opening, across about 3 ft undercounter, then up to the tower though an opening in my bar.
I am looking for suggestions and ideas of how to accomplish this feat. I am interested in putting a glycol system and while your cooled beer lines look good, spending $900 on a pump for one beer at 5-6 feet is out of the question. Someone once suggested an aquarium pump in a chamber in the fridge with glycol alcohol. Would this work? Can you give me any specifications for pump and tubing types? Would the container need to be glass or will plastic do?
